I've setup everything per your instructions, opened iTunes Radio, choose a streams and, as usual, after maybe 30', the system restarted into to the log in screen. (haven't' touched anything during that period)...Any ideas?

make sure you disabled the right pref. On top it says battery/ power adapter and adjust accordingly

I don't have a solution, but I can tell you that something's wrong here. You're Mac is not suppose to restart to the login screen. It shouldn't ever do that regardless of your settings. Are you sure you're talking about the login screen or the dialog box to unlock your screen?

Agreed, or at least I've never heard of it restarting and going to the initial log in screen. Look over the screen shots again, they should give you everything you need to know.

It's the screen where you can choose users: I have setup 2, one with a password (mine) and the other for a guest user. When this screen pops up, I can see a tick mark on mine.

Okay, I take back what I said about your Mac not auto logging out regardless of settings, it is possible. Try this. Go into System Preferences-Security, under the General tab make sure and uncheck (if it's IS checked) "Log Out After XX-minutes of inactivity".
